Abstract
A power storage module includes an electrode laminate in which bipolar electrodes are laminated and a sealing body formed of a resin. The bipolar electrode includes an electrode plate, a positive electrode provided on one surface of the electrode plate, and a negative electrode provided on another surface of the electrode plate. The sealing body is provided on a side surface of the electrode laminate to surround an edge portion of the bipolar electrode. The sealing body includes a first resin portion and a second resin portion. The first resin portion is welded to the edge portion of the bipolar electrode. The second resin portion surrounds the first resin portion from an outer side along the side surface. A mold shrinkage factor of the first resin portion is lower than a mold shrinkage factor of the second resin portion.
